3. The gravitational force between two objects (mass1 = 8 kg, mass2 = 4 kg) is measured when the objects are 10 centimeters apart. If the 8 kg mass is replaced with a 4 kg mass and the 4 kg mass is replaced with a 8 kg mass, how does the new gravitational attraction compare to the first one that was measured?

The field lines around one end of a bar magnet are shown below based on the diagram, what can you conclude about the pole of the magnet? a.is a south pole because the field hnes spread out from this end b.a north pole because the field lines spread out from this end c.a nouth pole because the field lines enter the magnet at this end d.is a north pole because the field lines enter the magnet at this end
